[Sigmetrics] Chinese versus US article output?

Thu Oct 1 07:52:50 EDT 2015

Dear colleagues, 

We have done these comparisons several times. Most recently: 

Leydesdorff, L., Wagner, C. S., & Bornmann, L. (2014). The European Union, China, and the United States in the top-1% and top-10% layers of most-frequently cited publications: Competition and collaborations. Journal of Informetrics, 8(3), 606-617. doi: 10.1016/j.joi.2014.05.002

Figures 1a and b: Percentages of world share of publications from China (blue), USA (red), and EU28 (green; in Figure 1a on the left), and in PPtop-1% and PPtop-10% (Figure 1b to the right). 

This is based on WoS data; see for more details the paper itself.

See also the discussion in: When can the cross-over between China and the USA be expected using Scopus data?  <http://www.researchtrends.com/issue25-november-2011/is-science-in-your-country-declining-or-is-your-country-becoming-a-scientific-super-power-and-how-quickly/> Research Trends, Issue 25, November 2011.

Best,

Loet

Subject: Re: [Sigmetrics] Chinese versus US article output?

It also depends on how you interpret and use the data. On articles and reviews indexed in Thomson Reuters Web of Science for 2014, China has maybe 250,000 documents to the USA with around 400,000. Run that back to 1981 and the ratio is more like 100:1 while in 2000 the ratio was 10:1 so the China trajectory is pretty clear (http://sciencewatch.com/grr/china). Of course, the commercial data sources draw on different sets of journals and don't use all other documents. The indicative 'growth' of China's research is also a switch from an applied, demand-led R&D base into one that publishes increasingly in anglophone journals rather than domestic reports.

Here is another way of looking at it. According to SCImago country rankings for 2014, the US output was 494,790 citable items while China had 438,601 or 89% of the US amount. See http://scimagojr.com/index.php Select country rankings, then 2014, then refresh. 

China's output has been growing rapidly for the last decade, so it looks like it could pass the US in just 2 or 3 years.

How does the present Chinese journal article output compare to the US? I recall discussions here some time ago about the Chinese output catching up with the US. Has it done so? Is it still growing?
